That statement is misleading and alarmist. Not everyone has visible half-moons (the white crescent-shaped area at the base of the nail, called the lunula), and in most cases, it’s perfectly normal.
🩺 Reality About Half-Moons
- The lunula is usually more visible on the thumbs and less visible on other fingers.
- Its visibility depends on nail thickness, skin pigmentation, and genetics.
- Some people naturally never see a half-moon, and it doesn’t indicate a health problem.
✅ When to Really Be Concerned About Nails
See a doctor if you notice sudden or unusual changes in your nails, such as:
- Color changes (blue, dark streaks, or very pale nails)
- Thickening or crumbling
- Separation from the nail bed
- Persistent pain, swelling, or infection
- Horizontal lines or indentations (like Beau’s lines) that develop suddenly
💡 Takeaway
- Lack of a visible half-moon is not an emergency.
- Healthy nails come in all shapes and sizes.
- Routine nail appearance should be monitored for changes over time, not just the presence of a crescent shape.
